After NAMLRD successfully reclaimed all of the coal sites that were inventoried on Navajo Nation trust lands and received coal certification in 1994, the Office of Surface Mining, Reclamation, and Enforcement (OSMRE) authorized NAMLRD to reclaim physical hazards associated with abandoned uranium mines (AUMs), such as open adits, trenches, pits and dangerous highwalls. NAML has successfully reclaimed hundreds of AUMs across Navajo Nation trust land under the OSMRE Surface Mining and Reclamation Act (SMCRA) of 1977.
In June 2018, the U.S. Environmental Protection Agency (EPA) awarded the NAMLRD program $888,000 to help assess and perform cleanup of AUMs on the Navajo Nation. “NAML’s staff of scientists and engineers are uniquely positioned to provide the expertise and perspective to address uranium contamination on the Navajo Nation,” said Mike Stoker, EPA Regional Administrator for the Pacific Southwest. See the news release “U.S. EPA awards Navajo Abandoned Mine Lands Program $888,000” for details.
On November 9, 2018 a Memorandum of Understanding (MOU) between the Navajo Nation EPA (NNEPA) and NAMLRD was signed to address cleanup of the 523 AUMs on the Navajo Nation. See “MOU signed between Navajo EPA and Navajo AML” for details.
